Help ID my symptom please?

Hi guys, I've been getting this weird symptom that's hard to even begin to describe, like a constant tensing of my muscles in my shoulder and lower neck, or like my muscles feel itchy, or ticklish, or kinda like a cramp that feels like when you hit your funny bone in my forearms and hands that seems to get triggered by the minutest amount of frustration or fiddlyness, even typing on a phone

What is it and how to make it go away
